Objective To analyze rick factors for postoperative recurrence of spontaneous pneumothorax surgery. Methods The clinic characteristics of 1128 patients who received spontaneous pneumothorax surgery in Tianjin Chest Hospital were collected from January 2009 to March 2015. The relationship between clinic characteristics and the pulmonary bullae was analyzed. Logistic regression analysis was used to assess factors affecting the postoperative relapse of spontaneous pneumothorax. Results The pulmonary bullae were found in 877 patients of 1128 during the operation. The incidence of pulmonary bullae was significantly high in patients with age below 25 years compared with patients over 25 years (P<0.05). The duration of surgery was significantly longer in patients with pulmonary bullae compared with that of patients without pulmonary bullae (P<0.05). Postoperative recurrence occurred in 21 cases, with a recurrence rate of 1.86%. Logistic regression analysis showed that pulmonary bullae, pleurodesis without pleura friction, delayed drainage duration (> 3 d) were independent risk factors of postoperative recurrence for spontaneous pneumothorax (P<0.05). Conclusion Pulmonary bullae, pleurodesis without pleura friction and delayed drainage duration are risk factors of postoperative recurrence for spontaneous pneumothorax, which should be paid more attention in clinic.%目的 分析原发自发性气胸术后复发的危险因素.方法 整理2009年1月—2015年3月天津市胸科医院胸外科单中心1128例自发性气胸手术治疗患者临床特征、围手术期相关因素及术后复发情况,分析以上因素与术中是否发现肺大泡之间的关系,Logistic回归分析评估自发性气胸术后复发的影响因素.结果 在所有1128例自发性气胸手术患者中肺大泡患者877例,肺大泡的发生率在年龄较小组(<25岁)高于年龄较大组(≥25岁,P<0.05);肺大泡组手术时间较无肺大泡组延长(P<0.05).手术后复发21例,复发率为1.86%.Logistic回归分析提示有肺大泡、术中胸膜固定时未行胸膜摩擦及术后引流时间延长(>3d)是自发性气胸术后复发的危险因素(P<0.05).结论 临床中对自发性气胸患者同时合并肺大泡、术中胸膜固定时未行胸膜摩擦及术后引流时间延长者要注意自发性气胸术后复发的风险.
